a,20,49×5,8-79,42÷3,8 =(20,49×5,8)-(79,42÷3,8) =118,842-20,9 =97,942 b,21,22+9,072×10+24,72 =21,22+(9,072×10)+24,72 =21,22+90,72+24,72 =136,66 Bình luận
a)
20.49 x 5.8 – 79.42 : 3.8
= ( 20.49 × 5.8 ) – ( 79.42 : 3.8 )
= 118.842 – 20.9
= 97.942
b)
21.22 + 9.072 x 10 + 24.72
= 21.22 + ( 9.072 × 10 )+ 24.72
= 21.22 + 90.72 + 24.72
= 136.66
Chúc em học tốt ^^
